specification of Letters Patent.

Application filed a rn 2a. 1914. Serial No. 834,977.

To aZZ whom it WMZj/ cow/rm Be it known that I, ()LAnnNCn L. TAYLOR, of Alliance, in the county of Stark and State of Ohio, have in vented certain new and useful Improvements in ShaftConplings; and I do hereby declare the following to be a full, clear and exact description of the in rention, such as will enable others skilled in the art to which it appertains to make and use the same.

lily invention relates to an improvement in shaft coupling designed particularly for connectngc -l the vibrating spindl A and roll in a rolling inill, the object being to provide a connection which will permit of a tree wabbling movement of the roll or spindle without any lost motion between the parts, thereby avoiding all pounding incidental to lost motion, in starting and stopping the mill.

4 A further object is to provide a construction wherein the rocking and sl ling move ment [of the coupling members will be smooth and uniform.

A further object is to provide a coupling that can be produced more economically and take up less room both in the direction of the aXis of the shaft and at right angles thereto, than any flexible coupling now in use.

\Vith thi'sc. objects in view my invention consists in the parts and combii'iat ou of parts and in the details of construction as will be more fully explained and pointed out in the claims.

In the acrompanyiing drawings, Figure l is a view in elevation of my improved coupling; Fig.1. 2 is a view of the members detached; Figs. 3 and 4: are end views of the coupling members; Fig. 5 is a view in transverse section taken centrally through the coupling and Figs. (3 and 7 are views in longitudinal section, Fig. 6 being ta ken through the jaws on one coupling member and Fig. 7 through the jaws on the! other member.

1 represents a spindle and 2 a roll or pinion shaft. If the spindlebe provided with couplings at each end, they would he alike. Each part to be coupled is provided with a coupling member 3, one of which has two oppositely located projecting jaws 4. and the other two similarly located jaws 5, the spaces between the jaws being slightly greater than the width of the jaws, so that when they are assembled, ample clearance will be provided for the vibrating or wahbli'ng mbvement of the parts.

Each jaw is provided on its inner face with a groove; all of which extend in the direction of the axis of the roll and spindle; The inner walls of grooves 6 in the jaws 4, are formed in the arc of a circle-while the inner walls of the grooves? in thejaws5j may be and preferably with the jaws of the other member without actual contact, by the knuckle ,S, which latter Patented Aug. 10, 1915 areyfiat and; parallel. The jaws of one couphngmember ntermesh and theyare locked together is in the shape of an X, with its jaw engaging menibers 9 located ninety degrees apart. -The'outer ends lOot' the aw ongaginggmembers 9, are

, in the arcs of a circle concentric with the y axis or center of theknuckle and also with".

the inner walls of the groovesfi in the jaws 4, so that when the knuckle is'in place within said jaws it is'free to turn; therein, or the coupling member can turn on it. Tllethroatof this coupling member 3, intermediate the jaws -.l-, is curved to conform-to the. cur iature ot the inner walls oi the aws, so that there is a. continuous guide way, inthe a rc of a circle, which is greater than .a ihalf circlejr from the outer end ofone jaw l: greatest diameter of a members i) of the knuckle, hence in order to insert the knuckle within said coupling mom'- 7 V jawto the other. I The distance between the outer endsof the less than the distance between the 7 pair of jawv engaging her, the jaw engagingmembers 9 which engage said jaws must be entered in the direction ofthe axis of the coupling member and then turned in a direction for itsmembers 9 to enter the grooves (i, and, when so entered latter may be coupledup to'the knuckle carried by the jaws l byan' cndwise movement of either part, and may be uncoupled by a straightaway movement from' the knuckle,

The knuckle is therefore the 'part which connects' one coupling member to the other, and when the parts are assembled it isi'nclosedand assen'ib'led, it will be lockedtherein and can only be ren'ioved by turning the knuckle until the aw engaging members are 111 llne' dinal moveinentand within the throats of said nember, and has 'a free rockin vzaiovement on the knuckle, so

- thatfwh' let etwo, 'inem'bei'fs. are locked. 1- against independent turning or rotary move- "inent, the universal connection between them permits either to wabble'or vibrate without afiecting the coupling or'the other member and'with'out creating anyispace which could of any .lost motion between the parts, j

andas'the knuckle is wholly Within the -t h'easpindle-and .roll and at right angles knuckle have olose' sliding" withinthe grooves;'therej can-beno lost motion conse-' thereto, than .afnyjcoupling' now .in "use! HAg'ain as. the jaw"engagin'g'. 'meinbersof the" quently all; damage-[due to pounding is r j I tegral'couplinghavmg two pairs of jaw avoided.- i

- It is evident 'in'an'y slight chang es"? might be resorted toin theirelative arrangement of,- parts shown. and described without departingfrom the spirit, and scope of my invention.-

Hence I would have it "under stood thatI-do notwish to confine myself to the exact construction and arrangement] of arts-shown and describedbut,

aving .fully described my invention what I claim-as-newanddesire to secure byLetters Patent, is l 4 1. A univers'al coupling consisting of two iiieinb'ei's-haviii'g in'terineshing jaws and an integral *k iucklefhaving a plurality of enes gaging members for the jaws of both membrs, the ends of said engaging members of the knuckle resting in recessed seats formed in the inner faces of the jaws, the seat in one jaw constructed to permit the engaging member to rotate-without longituv the other seat constructedfor. bbtlifiongitudinal and rotary moveine'ntof the ei'igaging'member, thereby perini t'ting' the two coupling members to be disconn 2. A universal coupling consisting of two members one Ofdlillllflli is provided with a said recesses being in the jaws provided on their inner iaces with recessed. seats the side"walls-of which are substanected by a straight endwise move:

members each having a pair of jaws with recessed inner faces, the inner walls of the engaging members, the ends of onepaii' being curved to coniorm to the curvature of L theiiiner walls of said recessed seats. 1

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
